Objective To study the effect of Shaoyaozhitong Mixture on stageⅢ-Ⅳendometriosis, and explore its mechanism. Methods Ninty-five cases of stageⅢ-Ⅳ endometriosis were randomly divided into three groups. The traditional Chinese medicine (TCM) group (31 cases) was treated with Shaoyaozhitong Mixture, the GnRHa group (31 cases) was treated with Triptorelin Acetate for Injection, while the expectant group (33 cases) received no medications. The changes of CA125, TNF-α and VEGF levels, visual pain score and SF-36 score, total effective rate, pregnancy and recurrence were compared. Results There were significant increases in CA125, TNF-α and VEGF levels, visual analogue pain score and SF-36 score in all the three groups after treatment (P<0.05). The decline of CA125, TNF-αand VEGF levels and visual analogue pain score in TCM group and GnRHa group was significantly faster and greater than that of the expectant group (P<0.05). The total effective rates of TCM group was 83.9%(26/31), GnRHa group was 87.1%(27/31), and expectant group was 60.6%(20/33), TCM group and GnRHa group were superior to the expectant group, respectively (P<0.05). The pregnancy rate was higher and recurrence rate was lower in TCM group and GnRHa group than that of expectant group, but there was no statistical difference (P>0.05). Conclusion Shaoyaozhitong Mixture is effective in treating endometriosis by inhibiting the growth of ectopic endometrium.

Objective To discuss the effect and safety about large dosage of tilofiban injection into coronary artery in patients with ST-segment elevated myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods A prospective study was conducted. Two hundred and eighteen patients with STEMI admitted into Cardiology Department of Taizhou Central Hospital were enrolled. According to the difference in dosage, they were divided into a large dosage tilofiban group (102 cases) and a routine dosage tilofiban group (116 cases). In both groups, they received the injection of load dosage of tilofiban into coronary artery during they underwent primary PCI, the load dosage being 25μg/kg in the large dosage group, and 10μg/kg in the routine dosage group. Afterwards, the dosage was kept on 0.15μg·kg-1·min-1 in both groups lasting for 18-24 hours. The flow of thrombolysis in myocardial infarction (TIMI) immediately after PCI, the return of ST-segment after operation for 2 hours, the rate of bleeding events, the rate of major adverse cardiac event [MACE, including death, re-infarction and target vessel revascularization (TVR)] and prognosis after operation for 30 days were observed. Results The ratios of the immediate reflow of TIMI 3 grade after operation and the return of ST-segment after operation for 2 hours in the large dosage tirofiban group were higher than those in the routine dosage tirofiban group [the ratio of the reflow of TIMI 3 grade:92.16%(94/102) vs. 81.90%(95/116), the ratio of the return of ST-segment after operation for 2 hours:89.22%(91/102) vs. 73.28%(85/116), both P < 0.05]. The ratios of re-infarction, TVR and the total MACE in 30 days after operation in large dosage tirofiban group were lower than those in the routine dosage tirofiban group [re-infarction: 0.98% (1/102) vs. 2.59% (3/116), TVR: 0.98% (1/102) vs. 2.59% (3/116), total MACE: 1.96% (2/102) vs. 6.03% (7/116), all P < 0.05]. There were no statistically significant differences in mortality and the bleeding events between the large dosage tirofiban group and routine dosage tirofiban group [mortality:0 (0/102) vs. 0.86%(1/116), bleeding events:1.96%(2/102) vs. 0.86%(1/116), both P>0.05]. Conclusion The injection of a large dosage of tilofiban into a coronary artery in patients with STEMI undergoing primary PCI is an effective and safe method to allow them to get more clinical benefits.

Objective To study the clinical characteristic of non puerperal mastitis and estimate the effect of anti-mycobacterial agents for non puerperal mastitis .Methods 22 cases of periductal mastitis and gran-ulomatous mastitis receiving anti-mycobacteria drugs therapy from Mar .2012 to Mar.2014 were retrospectively analyzed.Results All patients were female.The mean age was 30 years(ranging from 24 to 46 years).The main clinical manifestation of the 22 patients were 18 patients(81.8%)with mass, 20 patients(90.9%)with abscess, 15 patients(68.2%)with fistula and 9 patients(40.9%)with all of the above 3 symptoms.6 patients had incision and drainage of abscess and 2 patients had tumor resection before anti-mycobacterial therapy .All of the 8 patients had postoperative recurrence .All patients underwent anti-mycobacterial therapy with 3 to 16 months.11 cases (50.0%)patients were cured without recurrence until now .7 cases(31.8%) patients were improved markedly and they still received drug treatment .2 cases(9.0%)patients with tumor size reduced to 2 cm were ready to sur-gical resection.2 cases(9.0%)were lost to follow-up.Conclusion Patients with refractory non puerperal masti-tis can be treated with anti-mycobacterial agents with relatively long treatment time and can also avoid mastecto-my.

Objective:To investigate the effect of DKK1 on linearly patterned programmed cell necrosis (LPPCN) and vasculogenic mim-icry (VM) and the related molecular mechanism in non-small cell lung cancer (NSCLC). Methods:A total of 173 human NSCLC speci-mens were collected to detect LPPCN by H&E staining, detect VM with CD31/PAS double staining, and investigate DKK1 and related protein expression by immunohistochemistry. The clinical pathological significance of LPPCN, VM, and DKK1 and the correlation of them were analyzed. Human NSCLC H460-DKK1 cells were engrafed in nude mice to evaluate the influence of DKK1 up-regulation on VM and LPPCN in vivo. Results:Approximately, 14.45%(25/173) of NSCLC had VM and 49.71%(86/173) had LPPCN. 25.6%(22/86) of NSCLC cases in LPPCN-positive group formed VM. Both of VM and LPPCN were all correlated with poor differentiation, late TNM stage, easy recurrence and metastasis and poor prognosis in NSCLC. DKK1 expression in the VM-positive group and the LPPCN-positive group was higher than that in the VM-negative group and the LPPCN-negative group, respectively. DKK1, LPPCN, and VM were positive-ly correlated with VE-cadherin, MMP-2,β-catenin nuclear expression and Twist1. H460-DKK1 transplantation tumor model confirmed that DKK1 promotes the expression of VM and LPPCN and related proteins in NSCLC. Conclusion:The increase of theβ-catenin and Twist1 expression induced by DKK1 may promote the formation of LPPCN and VM in NSCLC.

Objective: To investigate the trend in mortality of malignant tumors in Xiaoshan District, Hangzhou City from 2017 to 2022, so as to provide insights into formulation of the malignant tumor control strategy. Methods: Data on mortality of malignant tumors in Xiaoshan District from 2017 to 2022 were collected through Hangzhou Municipal Chronic Disease Monitoring Management System, and the cause of death composition ratio and crude mortality were calculated. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010. The trend in mortality of malignant tumors were evaluated with average annual percent change (AAPC). Results: There were 13 301 malignant tumor deaths reported in Xiaoshan District from 2017 to 2022, accounting for 31.26% of the total cause of death and ranking the first among the causes of death. The crude mortality was 186.36/105 and standardized mortality was 106.63/105. There was no significant trend in the crude mortality of malignant tumors in Xiaoshan District from 2017 to 2022 (P>0.05), while the standardized mortality showed a tendency towards a decline (AAPC=-1.409%, P<0.05). The crude and standardized mortality of malignant tumors were higher in men than in women (241.40/105 vs. 133.37/105; 132.66/105 vs. 79.35/105; both P<0.05). There was no obvious trend in the crude mortality of malignant tumors in men (P>0.05), and the standardized mortality showed a tendency towards a decline (AAPC=-3.017%, P<0.05). While there was no obvious trend in the crude and standardized mortality of malignant tumors in women (P>0.05). The crude mortality of malignant tumors showed a tendency towards a decline among residents at ages of 15 to 44 years and 65 years and older (AAPC=-3.933% and -2.413%, both P<0.05). The crude mortality of malignant tumors was higher in men than in women among residents at ages of 0 to 14 years, 45 to 64 years and 65 years and older (all P<0.05). The five most common causes of death included lung cancer, colorectal cancer, liver cancer, gastric cancer and pancreatic cancer, accounting for 66.96% of all malignant tumors. The crude mortality of colorectal cancer from 2017 to 2022 showed a tendency towards a rise (AAPC=2.815%, P<0.05). Conclusions The standardized mortality of malignant tumors showed a tendency towards a decline in Xiaoshan District from 2017 to 2022. Management of malignant tumors should be given a high priority among men at ages of 45 years and older, and lung cancer, colorectal cancer, liver cancer, gastric cancer and pancreatic cancer were leading causes of death.

Objective: To investigate the mortality, probability of premature death and trends due to malignant tumors, cardio-cerebrovascular diseases, diabetes and chronic respiratory diseases in Xiaoshan District, Hangzhou City from 2015 to 2021, so as to provide the basis for the formulation of chronic diseases prevention and control strategies. Methods: The deaths of the four diseases in Xiaoshan District from 2015 to 2021 were collected from Zhejiang Provincial Chronic Diseases Surveillance Information Management System. The crude mortality, standardized mortality and probability of premature death were calculated. The trends in mortality and probability of premature death were analyzed using average annual percent change (AAPC), and the attainment of probability of premature death due to the four diseases was evaluated using the targets of probability of premature death control in 2025 and 2030. Results: Totally 36 130 deaths due to the four diseases were reported in Xiaoshan District from 2015 to 2021. The crude mortality and standardized mortality were 445.20/105 and 237.81/105, which appeared a tendency towards a decline (AAPC=-1.427% and -4.051%, both P<0.05), and the probability of premature death decreased from 9.99% to 7.82%, (AAPC=-4.123%, P<0.05). The standardized mortality of malignant tumors, cardio-cerebrovascular diseases and chronic respiratory diseases appeared a tendency towards a decline (AAPC=-3.017%, -4.999%, and -6.024%, all P<0.05), while there was no significant trend in the standardized mortality of diabetes (AAPC=-0.847%, P>0.05). The probability of premature death due to malignant tumors appeared a tendency towards a decline (AAPC=-4.167%, P<0.05), while there was no significant trends seen in the probability of premature death due to diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases (AAPC=0.638%, -5.250% and -2.022%, all P>0.05). The average probability of premature death due to the four diseases decreased by 4.00% each year, and decreased by 6.64% in 2025 and 5.42% in 2030 as predicted, which were both lower than the target values of 7.99% and 6.99%. Conclusions The mortality and probability of premature death due to the four diseases appeared a tendency towards a decline in Xiaoshan District from 2015 to 2021, with the probability of premature death of malignant tumors decreased significantly. It is predicted that the probability of premature death of the four diseases can reach the target in 2025 and 2030.
